Various forms of therapeutic superficial tissue manipulation have been practiced for thousands of years across cultures. Chinese use of massage dates to 1600 BC, and Hippocrates made reference to the importance of physicians being experienced with "rubbing" as early as 400 BC. There are references to massage in ancient records of the Chinese, Japanese, Arabic, Egyptian, Indian, Greek, and Roman nations. References to massage are also found in the Bible and the Vedas. Terms for massage include the French word masser , the Greek word for "knead," a Hindu word for "press," and an Aramaic word that means "to press softly." The technique that is currently called Swedish massage was developed in the 19th Century by Per Henrik Ling (1776-1839) as a combined form of massage and gymnastic exercises. Many different therapeutic techniques can be classified as massage therapy. Most involve the application of fixed or moving pressure or manipulation of the muscles/connective tissues of clients. Practitioners may use their hands or other areas such as forearms, elbows, or feet. Lubricants may be added to aid the smoothness of massage strokes. Techniques used in Swedish massage include (1) superficial stroking in a direction away from the heart or deep stroking towards the heart; (2) kneading in a circular pattern using fingers and thumbs; (3) deep muscle stimulation; (4) rhythmic movements such as slapping or tapping; and (5) vibration. Sports massage is similar to Swedish massage but is adapted specifically for athletes. Classical massage aims to provide calmness, relaxation, encourage self-healing, and revitalization. Many other variations and styles of massage or touch exist, often developed in specific geographic regions. Scientific research of massage is limited, and existing studies use a variety of techniques and trial designs. Firm evidence-based conclusions about the effectiveness of massage cannot be drawn at this time for any health condition.

Biofeedback is a purported technique for helping an individual become conscious of otherwise unconscious body processes. Through conveying information about blood pressure, heart rate, skin temperature, galvanic skin response (sweating), and muscle tension in real-time, biofeedback aims to raise awareness and conscious control of the related physiological (natural biological processes) activities. In essence, biofeedback attempts to use the mind to control the body. Neal Miller, a psychologist and neuroscientist who worked and studied at Yale University, is generally considered to be the father of modern-day biofeedback. In the 1950s, he came across the basic principles of biofeedback when doing animal experimentation conditioning the behavior of rats. His team found that by stimulating the pleasure centers of the rats' brains with electricity, it was possible to train rats to control phenomena ranging from their heart rates to their brainwaves. Until that point, it was believed that bodily processes like heart rate were under the control of the autonomic nervous system and not responsive to conscious effort. Biofeedback has been shown to be helpful in treating a variety of medical conditions including asthma, Raynaud's disease, irritable bowel syndrome, hot flashes, nausea and vomiting associated with chemotherapy, incontinence, headaches, irregular heartbeats (cardiac arrhythmias), high blood pressure, and epilepsy. Other common uses may include the treatment of stress and stress-related conditions such as anxiety and insomnia. Interest in biofeedback has fluctuated since its development in the 1960s. Today, it is becoming popular once more, possibly because of the general increase of interest in complementary and alternative medicine modalities.
